The case: Shane Franklyn Miller is suspected of gunning down his wife Sandy and daughters Shelby Miller, 8, and Shasta Miller, 4, in their Shingletown home in Shasta County on May 7 before fleeing 200 miles to the Mattole Valley. Authorities have confirmed that Miller made contact with a woman he had a past relationship with in Petrolia the day after his family was found dead, and his truck was later found on Mattole Road. High school friends and others who knew him during his time in Humboldt County say he has outdoor survival skills and knows the wilderness area where he was last seen.

Miller has a criminal record and served time in prison. Authorities consider Miller armed and dangerous.

Community members are encouraged to call the sheriff's office at 445-7251 or the tip line at 268-2539 if they see anything suspicious or 911, in the event of an emergency.

The other dozen outside agencies that joined the manhunt returned to their jurisdictions. Humboldt County Sheriff's Office deputies will continue 24/7 road patrols until further notice, Daniels said.

"Two deputies are out there at all times in case something comes up," he said.
